The knee is made up of four bones. The femur or thighbone is the bone connecting the hip to the knee. The tibia or shinbone connects the knee to the ankle. The patella (kneecap) is the small bone in front of the knee and rides on the knee joint as the knee bends.

A fracture is a condition in which there is a break in the continuity of the bone. In younger individuals, these fractures are caused by high-energy injuries, as from a motor vehicle accident. In older people, the most common cause is weak and fragile bones.

The two wedge-shaped cartilage pieces present between the thighbone and the shinbone are called menisci. They stabilize the knee joint and act as shock absorbers. A sudden bend or twist in your knee can cause the meniscus to tear.

Patellofemoral instability is the moving out of your patella or kneecap from its normal alignment in the knee.

Knee arthroscopy is a common surgical procedure performed using an arthroscope, a viewing instrument that helps your doctor to clearly view the knee joint, and diagnose or treat a knee problem. It is a relatively safe procedure, and a majority of the patients discharge from the hospital on the same day of surgery.

Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint are removed and replaced with artificial parts.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. When this ligament tears, unfortunately, it does not heal and often leads to the feeling of instability in the knee. ACL reconstruction is a commonly performed surgical procedure.

Anterior cruciate ligament (ACL) reconstruction hamstring method is a surgical procedure that replaces the injured ACL with a hamstring tendon. The ACL is one of the four major ligaments of the knee that connects the femur (thighbone) to the lower leg bone (tibia or shinbone) and helps stabilize your knee joint. It prevents excessive forward movement of the tibia in relation to the thighbone and limits rotational movements of the knee.

Anterior cruciate ligament (ACL) reconstruction patellar tendon is a surgical procedure that replaces the injured ACL with a patellar tendon. The ACL is one of the four major ligaments of the knee that connects the femur (thighbone) to the lower leg bone (tibia or shinbone) and helps stabilize your knee joint. It prevents excessive forward movement of the tibia in relation to the thighbone and limits rotational movements of the knee.

Unicondylar knee replacement is a surgical procedure that involves replacing a part of the knee joint with a prosthesis instead of the entire knee joint as in a total knee replacement.

Revision knee replacement surgery involves replacing part or all of your previous knee prosthesis with a new prosthesis. Although total knee replacement surgery is successful, sometimes the procedure can fail due to various reasons and require a second revision surgery.
